For the safest operation, Roku recommends only the use of the original power adapter provided with your Roku player model, or a power adapter by Roku that is specifically designed for your Roku player. Roku replacement power adapters can be purchased here.

Roku will not be responsible for any damage incurred as a result of using a non-Roku manufactured power adapter with your Roku player.
